Security Specialist (junior traineeship, medior, senior)

Computest was started by a group of friends 16 years ago. Today, this pleasant atmosphere is still there. We are nerds, but then again very sociable nerds. Many of us have healthy obsessions with tech, but that is part of our business. We are informal, friendly and prefer personal contacts. This is the best way to describe Computest. We are quite down to earth and honest. We may be a bunch of techies, but our new colleagues soon feel at home. (Certainly those who like get-togethers and the occasional joke.)
As we are growing fast, we need more techies. Would you like to join us?

What you will do as a Security Specialist

As a Computest Security Specialist you will advise organizations on the security of their IT systems. Your work may include external vulnerability assessments (pen tests), code reviews or configuration research. As a rule Computest Security provides short projects (1-2 weeks). In a short period of time, you will have to deal with many different organizations and types of applications.

  • As a Security Specialist you will test web applications. These tests are a combination of manual testing and skilful use of required automatic tools.
  • At the end of your investigation you will write a report with your findings to be presented to the client.
  • In addition to testing web applications, you will have the opportunity to specialize in a specific area of interest, such as mobile applications, office networking, Active Directory, or cloud security (AWS/Azure).

Our training program

For the real starters there is an extensive training program. Depending on your experience, you will follow parts of it or skip it altogether.

  • All specialists who start with us will be individually trained by experienced specialists, so you can master the Computest methodology. This training takes several months and is fully paid.
  • The first phase of the training will be class teaching and playing challenges.
  • The second phase of the training is shadow testing: you perform the same test as an experienced specialist, and afterwards we compare results.
  • Only when your results match those of the experienced tester will you proceed to the third phase and work for our customers. In this phase you will still receive individual support, and your results will be checked by an experienced specialist.
